water-soluble dye

Jar test for color removal of printing and dyeing wastewater with iron particle showed that main factor connecting with color removal are raw wastewater pH, dosage ratio of iron to water, reaction time, aeration, raw wastewater color and type of dye.

铁屑静态烧杯脱色实验表明，影响脱色的主要因素有：废水pH值、铁水投配比、反应时间、曝气、原水色度和染料种类。

A thin glass stick instead of capillary tube was used for the test of the synthesis process of a water-soluble dye by TLC, and the height of TLC was shortened, good results were achieved.
